Best Answer: Putting batteries in the freezer or refrigerator doesn't necessarily prolong their life. Alkaline batteries stored at room temperature self discharge at a rate of less than two percent per year. So normally refrigerating or freezing them will only help maintain their charge by a tiny amount.
Cold weather causes the reaction to slow down and can stop your battery from working. Hot weather can speed up the reaction and cause the battery to drain itself. so yes temp does effect battery life. but they can both be fixed by a quick jump unless your battery is completely dead. canman545 Â· 8 years ago. 1.
